The para‐selectiveC−H alkylation of aniline derivatives furnished with a pyrimidine auxiliary is herein reported. This reaction is proposed to take place via an N−H‐activated cyclometalate formed in situ. Experimental and DFT mechanistic studies elucidate a dual role of the ruthenium catalyst. Here the ruthenium catalyst can undergo cyclometalation by N−H metalation (as opposed to C−H metalation in
Chemoselective SNAr reactions of 4,6-dichloro-2-(methylsulfonyl)pyrimidine and several related electrophiles with amines and their derivatives are described. In the presence of weak bases anilines and secondaryaliphatic amines selectively displace the chloride group. Deprotonated anilines and their carbonyl derivatives displace the sulfone group. Sterically and electronically unbiased primaryaliphatic amines
